Question

求助，怎么用c#模拟键盘

Answer 1

1. 比较简单的方式

   使用system.windows.forms.sendkeys.Send()方春兄法发困哪送键击

   参见 http://msdn.microsoft.com/zh-cn/library/system.windows.forms.sendkeys.aspx
   

2. 比较复杂的方式：
   

WM_KEYDOWN = 0x0100;// 按下一个 键

WM_KEYUP = 0x0101;

// 释 放一个 键

WM_CHAR = 0x0102;

// 按下某 键 ，并已 扒尺袭发 出 WM_KEYDOWN ， WM_KEYUP 消息

using System.Runtime.InteropServices;
[DllImport("user32.dll", EntryPoint="SendMessageA")]
public static extern int SendMessage (IntPtr hwnd, int wMsg, IntPtr wParam, IntPtr lParam);

hWnd是窗口的句柄，0就是系统，wParam是键盘码

Answer 2

public enum KeyEventType
{
/// <summary>
/// 键盘按下
/// </summary>
KeyDown = 0x0000,
/大困知尺塌// <summary>
/// 扩展
/// </summary>
ExtendedKey = 0x0001,
/// <summary>
/// 键盘释放
/// </summary>
KeyUp = 0x0002
}

[DllImport("user32.dll"滚消)]
private static extern int keybd_event(Keys bVk, byte bScan, KeyEventType dwFlags, int dwExtralnfo);

keybd_event(KeyCode, 0, KeyEventType.KeyDown, 0);//KeyCode是键盘码
